Solar modules — and to a lesser degree solar inverters —are what people usually think about when considering a rooftop solar power system. But for many installers, it’s what’s under the panels that they worry about the most…especially after it rains. Solar racking or mounting systems are essentially the “glue” that holds the modules to the roof for 25+ years. And this “glue” has to be pretty strong to withstand the substantial wind loads that may systems experience, as well as periodic heat waves and freezing conditions. So it’s no surprise that for many installers, racking and mounting systems are where they spend the majority of their engineering, procurement and installation time.
